Phi Group is working with Sirius Remediation on enabling works at Woodside Quarry in Leeds to transform the site into a future residential development.

This enabling package included a large number of retaining walls, and Sirius employed Phi Group to carry out the design, supply and installation of both Permacrib timber crib and gabion basket retaining walls.

So far Phi Group has completed two Permacrib timber crib retaining walls with a face area of 750m2, and five gabion basket retaining walls that are 1,650m3 in volume.
